Apple security update 2018-002 10.13.6 fails on Mac Pro

Same problem here on MBP mid 2012 13 inch. Had to restore from time machine backup.

Yes, same. Guess, have to restore using Time Machine

I had the same issue. The booting process was interrupted by the failure of installing updates.

Fortunately, after 3 times of restarting, my mac was brought up successfully.

And to add to the previous post... Just updated a 2015 MBP, and it went through first try. This really is looking like they didn't test the update fully on Pre-2014 machines.

My fix on top of page 9 worked for me, you should give a try.

I see that 2018-003 is available for 10.13.6.

Anyone try it yet?

I have a mid-2014 iMac running High Sierra 10.13.6. When updating Safari and applying the security updates the process does not seem to complete.

The button says Installed but the process updatesoftwared is still pulling data from the Internet. The update had already pulled 1.88 Gb already.

I‘m stumped.

Thank you. It still took a while before an update button became actionable but I got Safari updated. The security update I passed on but that just sent the install into Download anyway so it’s pulling another 1.80Gb. That is painful because I’m on CenturyLink and they cannot provide more than a 1.5 Mbps connection. Real 21st century...

Addendum

Why this install is pulling another 1.8 Gb is puzzling.

Download is way too slow and after reading about having to reinstall OS I killed the download and will ignore the update until there is a replacement. This is the worst patch from Apple I've encountered.

This security update totally broke my brand new MacBook Pro running OS X high Sierra. Really worried apple becoming more & more trashy like Microsoft. Nothing works, my main work machine is now down. Does anyone at all test these things anymore under Steve cook?..speechless and extremely ****** at this fiasco.

Me too.

I had to reinstall OS after a big freak out.

Now its notifying me of the updates and I have no idea whether to install or not. Security updates are pretty important but this is crazy..

e too with Macbook

Thanks for a definitive answer on this. I can see that this is the case. One of the steps I was taking to use my bootable backup disk was holding the Option key that allows you pick a startup volume. I noticed that the first one was "Mac OS Installer". I was having no idea where this installer volume was coming from. I later realized auto updates was set in the App Store settings (I've turned those off now).

Anyway, there was a lot steps I took in this process, but I did make sure in System Preferences that my Startup Disk was the right one. I was taking pics along the way of different windows I was getting.

Just to clarify, my problem was hanging before the restart, not a failure to boot after applying the restart and update. I am not eager to repeat the experiment because it takes so long to restore from Time Machine, but I don't think there was a "MacOS Installer" disk present as a choice for "restore from Time Machine". I didn't keep as good records as markfug, but at one point I did explicitly choose a boot disk when exiting from a recovery mode boot where I did not either reinstall or restore.
